Frequently Asked Questions

What is a double cylinder?

A double cylinder requires a key to operate from both sides of the door. This provides maximum security as the door cannot be opened from the inside without a key — making it ideal for doors with glass panels nearby where a burglar could otherwise break the glass and turn an inside knob to gain entry.

What is the difference between a double cylinder and a knob cylinder?

A double cylinder (QS1103B) requires a key from both sides — maximum security but requires a key for exit. A knob cylinder (QS1108BL) uses a key outside and a turn knob inside — more convenient for quick exit but less secure where glass is nearby.

Is a lock included with this cylinder?

No. This is a cylinder only. The lock body must be purchased separately. This cylinder is compatible with the QS6055/1B Heavy Duty Mortice Latch Bolt & Deadbolt.

This is a 60mm cylinder designed for use with 60mm mortice locks. Confirm your lock’s cylinder size before ordering.
